Problem
A 2.0 L rigid flask contains N₂(g) at 2.0 atm and 300 K. A separate 3.0 L rigid flask contains O₂(g) at 1.0 atm and the same temperature. The stopcock between the flasks is opened, allowing the gases to mix while the temperature remains 300 K and the total volume becomes 5.0 L. What is the partial pressure of N₂ after equilibrium is reached?
(a) 1.40atm
(b) 0.56atm
(c) 0.80atm
(d) 0.93atm
